All new components will be read out via a newly developed system featuring an application called the Software Readout Driver (SW ROD), which will run on a commodity server receiving front-end data via the Front-End Link eXchange...

Precision calorimeters consisting of inorganic crystal scintillators have been playing an important role in the experimental high energy physics (HEP) experiments. In the last two decades, it faces challenges of the hostile radiation environment expected at the HL-LHC, the unprecedented event rate expected at accelerator based rare process search experiments and the low cost required by the...

The performance of ATLAS SemiConductor Tracker (SCT) in Run-2 at Large Hadron Collider (LHC) has been reviewed during the current long shutdown. The LHC successfully completed its Run-2 operation (2015-2018) with a total integrated delivered luminosity of $156~{\rm fb^{-1}}$ at the centre-of-mass $pp$ collision energy of $13~{\rm TeV}$. The LHC high performance provide us a good opportunity...

The successful running of the technological prototype of the Semi-Digital Hadronic CALorimter (SDHCAL) developed within the CALICE collaboration and proposed to equip the future ILD detector of the ILC has provided excellent results in terms of energy linearity and resolution but also tracking and PID capabilities.
To validate completely the SDHCAL option for ILD, a new R&D activities have...

Muography is a novel imaging technology to reveal density structure of hill-sized objects. The cosmic muons lose their energy and penetrate hundreds of meters into the ground, thus their differential local flux correlates with the density-lenght they traveled through.
Exploiting the high flux around the zenith the imaging of the internal structure of hills could be done underground. Various...
